Why is the fact that Turkey was built upon genocide not talked about more?

The republic of Turkey, founded in 1922, was purely made possible by the expulsion and genocide of pretty much all non turkish peoples in the ottoman empire that preceded it. The horrific Armenian genocide, the Assyrian genocide, the Greek genocide and the Albanian genocide, led to millions upon millions of deaths in the empire that led it to become a Turkish Ethnostate. These genocides were actually in fairly modern times (late 19th - early 20th century) when people had already started to become more free and genocide was internationally condemned. If these horrific events, far worse than many other genocides, led to the creation of Turkey then why did so many countries flock to get great relations with Turkey and everything was pretty much forgotten about afterward? It doesn’t really sit right with me.
